Boys are always on the move, wrestling, jumping, hopping, etc. They are physical. Boys will tell you what they are thinking but they don't tell what their day was like. Boys are easy to dress, jeans and tops, sneakers, dress shoes and they are all set.
Girls whine and whine and whine. You are left to figure out what is bothering them. Girls are more expensive to buy clothes for because they need dresses,skirts, slacks, jeans, dress shoes, everyday shoes, sneakers, tights, bows, ribbon.
Once they hit the teenage years and are going in cars and getting their license, you worry about boy or girl the same.
